I hear from many people that they have problems sleeping, I have never ever had that problem. Imho the big difference was almost always them telling me: they fret about not being able to sleep vs. me telling them: I can truly enjoy just getting into bed and I sometimes wrestle to not fall asleep because that feeling of being tired and hitting the bed is just so nice I want to extend the time I experience it... The wrestle is always useless because sleep comes very fast.

Even when I don't fall asleep immediately I can enjoy taking the time to think about work or plan the next day or think about future vacations or what I'm going to do to my home server when 18.04 comes out or the latest episode of Isaac Arthur [0], there are many nice things to think about with little else on the mind. It's almost a shame sleep disrupts my train of thought sometimes :)

I'm a bit of a fretter myself but never about sleep.
